With a mass below 5 Earth masses, a density of 3.2, and a semi-major axis of 0.0389 astronomical units, Kepler-968 b could, potentially, be an ocean world - a planet with no dry land.

At 3.498 Earth masses, Kepler-968 c is a so called Super Earth. Super Earths could be terrestrial worlds like Earth, but they could also be ocean worlds or terrestrial worlds wrapped in a substantial atmosphere, in which case some refer to them as Mini Neptunes.
